Looking back on electrical systems stocks’ Q3 earnings, we examine this quarter’s best and worst performers, including Napco (NASDAQ: NSSC) and its peers.

Like many equipment and component manufacturers, electrical systems companies are buoyed by secular trends such as connectivity and industrial automation. More specific pockets of strong demand include Internet of Things (IoT) connectivity and the 5G telecom upgrade cycle, which can benefit companies whose cables and conduits fit those needs.

Market Update

In response to the Fed's rate hikes in 2022 and 2023, inflation has been gradually trending down from its post-pandemic peak, trending closer to the Fed's 2% target. Despite higher borrowing costs, the economy has avoided flashing recessionary signals. This is the much-desired soft landing that many investors hoped for. The recent rate cuts (0.5% in September and 0.25% in November 2024) have bolstered the stock market, making 2024 a strong year for equities. Donald Trump’s presidential win in November sparked additional market gains, sending indices to record highs in the days following his victory. However, debates continue over possible tariffs and corporate tax adjustments, raising questions about economic stability in 2025.
